Dactyl

The Dactyl uses the Teensy Loader.

Linux users need to modify udev rules as described on the Teensy Linux page. Some distributions provide a binary, maybe called teensy-loader-cli.

To flash the firmware:

Build the firmware with make handwired/dactyl:<keymapname>, for example make handwired/dactyl:default
This will result in a hex file called handwired_dactyl_<keymapname>.hex, e.g. handwired_dactyl_default.hex
Start the teensy loader.
Load the .hex file into it.
Put the Teensy in firmware-loading mode:
- If your current layout has a RESET key, press it.
- If you lack a RESET key, press the reset button on the Teensy board itself.
Click the button in the Teensy app to download the firmware.

To flash with ´teensy-loader-cli´:

Build the firmware as above
Run <path/to/>teensy_loader_cli -mmcu=atmega32u4 -w handwired_dactyl_<keymapname>.hex
If you like, you can do both at once: make handwired/dactyl:<keymapname>:teensy
Put the Teensy in firmware-loading mode:
- If your current layout has a RESET key, press it.
- If you lack a RESET key, press the reset button on the Teensy board itself.
